In the first run I acquire the Displacement, Oload and SPCForce from all Elements, Force and Stresses from Element Set 1 in Subcase 1 and SC 2.
Do I Restart and analyze a Subcase 3 after Subcase 1 (with param,loopid and param,subid) I get ALL the results only for the 1st load step of SC 3 and...

That thing keeps me busy all day!
I downloaded the 300 nodes Demo on NEiNastran and did it there.
What is the iterative solver (PCGLSS)?
I exported the analysis model the way I know as linear static and I experience the same results you decribed,
with AUTOSPC,NO the ROD-node has...
Is this of any help to the problem described?
No, zero stiffness is not the problem, with J!=0 Nastran still delivers a result.
I simplified the modell again, no more RBE3, just four plate elements and the rod.
Why does it solve?
PARAM,AUTOSPC,NO
PARAM,MAXRATIO,1.E+8
PARAM,GRDPNT,0
CORD2C...
Hi community,
i have some kind of trouble using a ROD in NASTRAN.
My problem is a completed analysis where i thought a fatal error has to occur.
Its a bench-scale model and is as follows:
A square plate of 6x10 plate elements with isotropic material constrained with SPC DOF 1-6 at one end. The...
